ATOMIZER.

SPECIFICATION forming part. of Letters Patent No. 251,720, dated January 3, 11882. 1

Application filed July 2, 1881. (ModeL) To all whom it may concern:

Be it known that I, RHODES LOOKWOOD, of Charlestown, county of Suffolk, State of Mas sachusetts, have invented an Improvement in Atomizers, of which the following description, in connection withthe accompanyingdrawing, is a specification.

My invention relates to atomizers, and has for its object to socoustruct an atomizer that it can be readily cleaned, and to make the nozzle adjustable, so that the spray mayissue in any direction therefrom as is needed when used in connection with the nasal or throat'passages for medical or other purposes.

The invention is embodied in an atomizerin which the liquid-passage is located within the airtuhe, and the said air-tube is provided with a detachable tip containing an orifice directed across the orifice of the liquid-tube in the usual manner, the said tip being also provided with a passage, through which the jet-piece of, the liquid-tube passes. The said jet-piece is providednvith a shoulder which engages a seat upon the inside of the said tip, to thus maintain the extreme pointor orifice of the liquidjet piece in the same position relative to the orifice of the air-passage, and to prevent escape of air from the air-tube around the liquid-jet pieces. The said tip is adapted to be rotated upon the end of the air tube or passage, so that the current of air from its orifice may cross theliquid-orifice and throw the spray therefrom in any desired direction. As herein shown, the said tip is connected with the end of the airtube by screw-threads, so that in turnin git to change the direction of the spray a slight 1ongitudin al movement is produced upon the said tube, and the liquid-tube is made yielding, so that in'this longitudinal movement its jet-piece will always remain in engagement with the inside of the said tip, and in the same relative position thereto.

The drawing shows, in vertical section, an atomizer constructed in accordance with my invention.

The stopper-piece a, provided with a bushing, 1), of cork or other suitable material to enter the neck of the liquid-reservoir o, is provided with the usual fine air-inlet passage, 2, and has connected with it at its upper end the main air-tube d, preferably bent at an angle to the axis of the reservoir 0, for convenience in applying the spray at any desired point. The said stopper-piece a has a longitudinal passage, (1, through it in continuation of the air tube (1, into which the air enters through the pas'sage3 from the usual forcing apparatus, e.

The liquid-pipe f is placed concentrically within the air tube and passage (1 d, and the suction-pipef is fitted upon the outside of the passagefand inside of the passage (1, thus closing the latter and forming a continuation ot the liquid-passage f and maintaining the saiddiquid-passagc in proper position with the air-passage.

At the end of the liquid passagef is a jetpiece, g, fitted therein and having the fine passage and orifice necessary to produce a proper atomizing action. c

The air-tube d is provided with a tip, h, (shown as screwed thereon,)and provided with an orifice, i,directed across the end of the jetpiece g, which passes through an opening, 4, in the said tip it, provided with a tapering seat at 5, to receive a corresponding shoulder upon the jet-piece g, which thus tightly closes the passage 4, preventing the escape of air therethrough around the jet-piece g. By turning the tip h its orifice i can be brought in any desired angular position relative to thejet-piece j, so as to throw the spray in any desired direction, it being shown in full lines in proper position to throw it down, as when used for treating the throat-passages, and in dotted lines to throw the spray upward. Owing to the curve in the pipes dfand the elasticity of the latter the shoulder of thejet-piece y will remain in engagement with the seat 5 in the tip it when the latter is turned for about a single revolution on its screw-threads to vary the direction of the jet of spray, and the months of the orifices g and twill be retained in the proper relation. When the tip h is removed by unscrewing it the jet-piece y can he withdrawn from the end of the pipefand the sediment,which naturally collects at the inner end, 6, of the said jet-piece, can be readily removed from the pipe f, which is of uniform bore throughout, and the jet-piece itself may be readily cleared by passing a wire through it, in case the particles have collected within its passage. If,however,thesaidjet-pieceweremade undetachable from the pipe f, as is now commonly practiced, it would be very difficult and almost impossible to dislodge the sediment c01 lected at the point where the passage contracts to form the orifice, as at 6, since insertinga wire through the said orifice would merely dislodge the particles temporarily so that they would remain in the end of the pipe fnear the orifice ready to clog it as soon as the atomizer is again operated.

' I am aware that an atomizer has been made provided with a single removable tip containing both the air and liquid orifices, and al that an independent removable tip has been used for the air-passage in an atomizing apparatus in which the liquid-passage is continuous to its orifice, which is undetachable.

I claim- 1. The air-tubeand its tip free to be rotated thereon, the said tip being provided with an air orifice and central opening, combined with the liquid-tube and its jet-piece passing through the said central opening, substantially as and for the purpose described.

2. The air-tube and its tip free to be rotated thereon, the said tip being provided with an air-orifice and central opening and seat, combined with the liquid-tube and its jet-piece passing through the said central opening, and providedwith a shoulder to engage the said seat, substantially as and for the purpose deand an air-forcing apparatus to force air through the said air-tube and its tip, substantially as and for the purpose described.

In testimony whereofI have signed my name to this specification in the presence of two sub- SCI ibing witnesses.
